Auxiliary tool for independent temperature rise test of solid-sealed polar poles

Abstract

The invention discloses an auxiliary tool for independent temperature rise test of solid-sealed polar poles, comprising support rods screwed in screw holes of a solid-sealed polar post mounting base;an adjuster is connected to a connection rod of an insulating tie rod of a sold-sealed polar post; the adjuster moves axially along the connection rod. The auxiliary tool also includes a fixing plate;the fixing plate is provided with holes corresponding to the support rods and the connection rod, and the support rods and the connection rod are nested in the fixing plate; the end, far away from the solid-sealed polar post, of each support rod is provided with a limiter; the adjuster is positioned at the end close to the insulating tie rod. The auxiliary tool may replace a vacuum breaker to apply required rated overtravel to a solid-sealed polar post during temperature rise test, so that rated pressure is applied to a contact of the solid-sealed polar post. The auxiliary tool allows temperature rise test verification to be performed independently with no need for mounting a solid-sealed polar post on a vacuum breaker. The auxiliary tool saves cost, is simple and easy to operate, and allows the temperature rise verification process of the development process of solid-sealed polar posts to be shortened.

Description

technical field [0001] The invention belongs to the technical field of solid-sealed poles, and in particular relates to an auxiliary tooling for independent temperature-rise tests of solid-sealed poles. Background technique [0002] In the development process of the solid-sealed pole, it is necessary to complete relevant type test verification, including insulation test, breaking test, temperature rise test, mechanical life test and other items. The above-mentioned test items need to install the solid-sealed pole on the vacuum circuit breaker at the relevant type test station. In order to speed up the research and development progress, if conditions permit, manufacturers of solid-sealed poles will purchase some verification equipment, such as temperature rise test benches, etc., for preliminary verification, so as to improve product design and process based on test data in a timely manner, thereby Accelerate the development progress of the solid-sealed pole. However, durin...
